"Upon installation of this kit I found out that the stock tranny had already been replaced with a Tremec 5 Speed. But this kit fit like a glove. Had the whole process completed within a couple of hours and have never been more satisfied. My average mileage has increased by 2-3 miles per gallon with a smooth easy shift each time. No chatter no rattle just get up and go."posted by: Jack on April 17, 2014
